[Tex/LaTex] TikZ set node label position more precisely

labelsnodestikz-pgf

This seems like it should be really easy but I can't seem to find it anywhere…

I'd like to be able to fine-tune the positioning of a node label.

I'm aware of the \node[label=above/below/etc:{label}] (x) {}; syntax, but that doesn't seem to give you many options on where the label goes. I'd like to be able to place the label slightly closer or farther away, or maybe in a direction other than the 8 presets available.

\tikz[label distance=x] isn't a good solution because I need it to be node-specific.

You can define the direction of the label by using label=<angle>:<label text>. To specify the distance on a per node distance, you have to supply it to the label options: label={[label distance=<distance>]<angle>:<label text>}

\documentclass{article}
\usepackage{tikz}

\begin{document}
\begin{tikzpicture}[
    every node/.style=draw,
    every label/.style=draw
]
\node [label={[label distance=1cm]30:label}] {Node};
\end{tikzpicture}
\end{document}

The let command is useful here and allows for "inline computation":

\begin{tikzpicture}
  \foreach \i in {0,...,9} \draw (\i*36:2cm) node(\i){\i};
  \foreach \i in {0,...,9} \draw let \n1={int(mod(\i+2,10))} in (\i) -- (\n1);
\end{tikzpicture}

TikZ is very well integrated to TeX and you can use the same methods to modify some texts. For example you can use TeX's groups outside the tikzpicture environment or inside. You can use specific options inside a tikzpicture environment or inside a node. The main rule is that the text inside a node used the font defined outside if you don't use a specific option to change the font.

Now to put some text right the main node, you can use label= ... to define a label node or you can use the positioning library or you can use anchor=

\documentclass[11pt]{scrartcl}  
\usepackage[utf8]{inputenc} 
\usepackage{fourier,tikz}
 \usetikzlibrary{positioning}
\begin{document}  
  Font  by default

\begingroup 
\ttfamily\small
\begin{tikzpicture}
\node {Text in he node};
\end{tikzpicture} 

After the \emph{tikzpicture} but inside the group. 
\endgroup

Outside the  \verb+tikzpicture+ and outside the group.

\begin{tikzpicture}
  \node[font=\huge\bfseries] {Text in he node};
\end{tikzpicture}

\begin{tikzpicture}
 \begingroup \bfseries\small
  \node {First node};
   \endgroup  
  \node at (0,-1) {Second node}; 
\end{tikzpicture} 

\begin{tikzpicture}
  \node[draw,label={[align=left]right:right label\\ok}] {Main label};
\end{tikzpicture} 

 \begin{tikzpicture}
  \node[draw] (main){Main label}; 
  \node[right=0pt of main] (sub){Sub label};
\end{tikzpicture} 

 \begin{tikzpicture}
  \node[draw] (main){Main label}; 
  \node[anchor=west] at (main.east){Sub label};
\end{tikzpicture}   
\end{document}
